For some atheists, it's enough to simply not believe in God. Some people believe, but you don't. And that's OK.Other atheists, however, find themselves constantly being asked to justify why they don't believe in God, to explain how they can possibly have morals without believing in God, to respond to various arguments that supposedly prove the existence of God, to acknowledge that America was founded as a "Christian" nation, etc. And if you don't have a background in philosophy, formal logic, comparative religions, ancient history, and various scientific fields, it can be a bit daunting to attempt to respond to questions and assertions like these.Well, fear not! "Common Sense Atheism" is a collection of original essays that address these issues and many others in clear and easy to understand language, with just a dollop of humor to make it all go down smoothly. These essays will help you understand and explain to others why a lack of belief in God really is the only rational choice.After all, you shouldn't need a PhD to defend your lack of belief.
